[PDF] Preheating of silicic acid in silica sol production

2020/8/29Silica sols dispersed in water are produced by AkzoNobel Specialty Chemicals. A recipe for the manufacturing of the specific sol studied in this thesis is provided by AkzoNobel. The production of the studied sol includes ion exchange of sodium silicate to silicic acid. Silicic acid then polymerizes and grows to spherical particles by a condensation reaction. To reach a specific size of the sol Get price

Stber process

One major advantage of the Stber process is that it can produce silica particles that are nearly monodisperse, and thus provides an ideal model for use in studying colloidal phenomena. It was a pioneering discovery when first published, allowing synthesis of spherical monodisperse silica particles of controlled sizes, and in 2015 remains the most widely used wet chemistry approach to silica Get price
